Chen Lei's body is now as hard as divine gold, and can be said to be immune to all evil. The cold and damp air here does not cause any harm to him.
However, for ordinary warriors, staying here for a long time may cause them to develop incurable diseases for the rest of their lives. Therefore, these people can only stay in such an environment for three years. If they stay here for too long, their lives will be in danger.
This is just one of the dangers in the mine. There are other dangers. For example, some people once dug out a nest of magical insects while digging a mine. As a result, it caused the biggest disaster on Qinglong Island. Under that nest of magical insects, as many as 70% of the miners in the mine died directly.
In addition to the divine insects, there are also some large ferocious beasts that feed on dragon crystals, which are also extremely difficult to deal with. Who knows when these beasts will get into the mine. Faced with these beasts of the second or third level of Martial Emperor, the miners have no ability to fight back and can only be slaughtered and eaten.
Similarly, there is the danger of landslides. Sometimes, once a landslide occurs, all the miners will be crushed into meat paste. The ores here are extremely heavy. Once a landslide occurs, even gods cannot save them.
Therefore, in the mines of Qinglong Island, the death rate of miners remains high, almost as high as over 50%.
It is precisely because of such a high mortality rate that the miners on Qinglong Island are paid such high wages. It can be said that such high wages are simply buying lives.
Chen Lei entered the mine. The dim mine was not a big problem for Chen Lei. With his vision, even without a trace of light, he could see the darkness as day.
Chen Lei was carefully examining these mines, looking for the direction of the mineral veins.
Chen Lei also has an extraordinary understanding of mineral veins, so he can easily find where the dragon crystal output is the highest and most abundant.
Chen Lei waved the dragon-patterned gold mining pickaxe in his hand, and with a slight wave, large pieces of ore were chiseled off. Then, Chen Lei swung the hoe like the wind, and in the blink of an eye, he peeled off the stone skin on the outside of a huge piece of ore, revealing a fist-sized piece of dragon crystal stone.
According to Qinglong Island's requirements for miners, as long as he can dig out ten pieces of such dragon crystal stones every day, he will be considered to have completed the task.
This kind of task is easy for Chen Lei.
However, Chen Lei came here not to work as a miner for Qinglong Island, but to look for Qinglong Grass and Qinglong Rejuvenation Technique. At the same time, he also wanted to see what the mystery of this Dragon Crystal Stone was.
Playing with the dragon crystal in his hand, Chen Lei felt that there was a strange power contained in the dragon crystal.
This strange power possesses an extremely powerful active substance. Once absorbed and refined, it will greatly increase one's recovery ability.
Chen Lei tried to absorb and refine the energy in this piece of dragon crystal.
Finally, after Chen Lei absorbed all the energy in the dragon crystal, he could suddenly feel that the vitality in his body had increased a lot. This was the energy contained in just a small fist-sized piece of dragon crystal. If there were a huge amount of dragon crystal, I really don’t know to what extent he would improve.
